Pre-disassembly Procedure Before proceeding with the disassembly procedure, perform the steps listed below: Turn off the system and all the peripherals connected to it. Unplug the power cord from the power outlets. Unplug the power cord from the system. Unplug all peripheral cables from the system. Place the system unit on a flat, stable surface.

Removing the Side Panel Remove the two screws located on the rear edge of the side panel. Slide the panel back about 2.5 cm (1.0 in) to release it from the chassis notches, then detach the panel from the chassis. Put the side panel aside for reinstallation later.

Removing the Front Bezel Release the front bezel retention tabs from the chassis interior. Pull the front bezel away from the chassis. NOTE: The bezel can’t be entirely removed until completed below step.due to the other end of power cable connecting with motherboard.

Removing the Heat Sink Fan Assembly WARNING:The heat sink becomes very hot when the system is on. NEVER touch the heat sink with any metal or with your hands. Use a long-nosed screwdriver to loosen the four screws on the heat sink, in the order as shown below. Note :CPU Fan has been highlighted with the yellow rectangle as above image shows.Please detach the CPU Fan and follow local regulations for disposal.

Disconnect the fan cable from the mainboard. Remove the heat sink fan assembly then lay it down in an upright position—with the thermal patch facing upward. Do not let the thermal patch on the heat sink fan assembly touch the work surface. Use an alcohol pad to wipe off the thermal grease from both the heat sink and the processor.

Removing the Processor IMPORTANT:Before removing a processor from the mainboard, make sure to create a backup file of all important data. WARNING:The processor becomes very hot when the system is on. Allow it to cool off first before handling. Release the load lever. Lift the load lever and load plate to the fully open, upright position (1) and (2).

Pull out the processor from the socket. IMPORTANT: If you are going to install a new processor, note the arrow on the corner to make sure the processor is properly oriented over the socket. Chapter 3...

Removing the Optical Drive and the Hard Disk Drive Disconnect the SATA (1) and power (2) cables from the rear of the optical drive. Disconnect the other end of the SATA cable from the mainboard. Chapter 3...

Removing the Memory Modules IMPORTANT:Before removing any DIMM from the memory board, make sure to create a backup file of all important data. Press the holding clips on both sides of the DIMM slot outward to release the DIMM(1). Gently pull the DIMM upward to pull it away from the M/B(2). Note: Circuit boards >10 cm²...

Removing the Power Supply Disconnect the ATX power supply cables from its mainboard connector. Squeeze on the retaining latch (1) attached to the cable end of the connector. Grasp the cable end of the connector and pull it straight up (2). Remove the screw that secures the power supply to the chassis.

Remove the three screws that secure the power supply to the rear panel. Pull the the power supply module toward the front. Tilt the power supply module slightly to the right and lift it out of the chassis. Chapter 3...

Remove the two screws that secure the front I/O and card reader assembly to the bracket. Remove the front I/O and card reader assembly from the bracket. Note: Circuit boards >10 cm² has been highlighted with the yellow rectangle as above image shows. Please detach the Circuit boards and follow local regulations for disposal.

Removing the Mainboard Remove the six screws that secure the mainboard to the chassis. Note: Circuit boards >10 cm² has been highlighted with the yellow rectangle as above image shows. Please detach the Circuit boards and follow local regulations for disposal. Lift the board from the chassis.

Punching in IO Shield then you can remove it. Remove the RTC battery. Note:RTC battery has been highlighted with the yellow circle as above image shows.Please detach the RTC battery and follow local regulations for disposal. Chapter 3...

Assembly Requirements To assemble the computer, you need the following tools: Wrist grounding strap and conductive mat for preventing electrostatic discharge • Flat-blade screwdriver • Philips screwdriver • Hex screwdriver • Plastic flat-blade screwdriver • Plastic tweezers • NOTE: The screws for the different components vary in size. During the assembly process, group the screws with the corresponding components to avoid mismatch when putting back the components.

Assembly Procedure Before proceeding with the assembly procedure, perform the steps listed below: Turn off the system and all the peripherals connected to it. Unplug the power cord from the power outlets. Unplug the power cord from the system. Unplug all peripheral cables from the system. Place the system unit on a flat, stable surface.

Removing the Side Panel Remove the two screws located on the rear edge of the side panel. Slide the side panel toward the back of the chassis until the tabs on the cover disengage with the slots on the chassis. Lift the side panel away from the server and put it aside for reinstallation later.

Reinstalling the Main Board Slide the mainboard into the chassis, with the I/O ports of the mainboard extruding from their port holes, then lower the mainboard in place. Make sure the screw holes on the main board are aligned with those on the chassis. Secure the mainboard with four screws.

Reinstalling the Power Supply Tilt the power supply module into the chassis (1) and push the power supply module toward the rear (2), with the power connector extruding from the rear panel. Secure the power supply to the rear panel using three screws. Chapter 3...

Reinnstalling the Memory Open the holding clips on both sides of the DIMM slot outward. Insert the memory module into the DIMM1 slot (1) and then press it down until it clicks into place (2). If a second memory module is available, install it in the DIMM2 slot by repeating step 1. Chapter 3...

Non- Acerproducts, prototype cards, or modified options can give false errors and invalid systemresponses.

System Check Procedures Power System Check If the system will power on, skip this section. Refer to System External Inspection. If the system will not power on, do the following: Check if the power cable is properly connected to the system and AC source. •...

Beep Codes Beep codes are used by the BIOS to indicate a serious or fatal error to the end user. Beep codes are used when an error occurs before the system video has been initialized. Beep codes will be generated by the system board speaker, commonly referred to as the PC speaker.

Checkpoints A checkpoint is either a byte or word value output to I/O port 80h.The BIOS outputs checkpoints throughout bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoint sare very useful in aiding software developers or technicians in debugging problems that occur during the pre- boot process.

Bootblock Recovery Code Checkpoints The Bootblock recovery code gets control when the BIOS determines that a BIOS recovery needs to occur because the user has forced the update or the BIOS checksum is corrupt. The following table describes the type of checkpoints that may occur during the Bootblock recovery portion of the BIOS. NOTE: Checkpoints may differ between different platforms based on system configuration.

BIOS Recovery AMIBIOS supports a "recovery flash" mode, which can be used to flash update a BIOS from the boot block. This is used to update a BIOS image without the need to boot to an operating system. The following is the process that user should follow to flash BIOS ROM.

Jumper Setting This section explains how to set the jumper for correct configuration of the main board. Jumpers with more than one pin are numbered. When setting a jumper, ensure that the jumper caps are placed on the correct pins. The following illustration shows the location of CMOS1.
